Carotenoids and chlorophylls are photosynthetic pigments synthesized in plastids from metabolic precursors provided by the methylerythritol 4-phosphate (MEP) pathway. The first two steps in the MEP pathway are catalyzed by the deoxyxylulose 5-phosphate synthase (DXS) and reductoisomerase (DXR) enzymes. While DXS has been recently shown to be the main flux-controlling step of the MEP pathway, bo...

Recent evidence suggests that 4.5- and even 3.5-month-old infants realize that objects continue to exist when hidden. The goal of the present experiments was to obtain converging evidence of object permanence in young infants. Experiments were conducted using paradigms previously used to demonstrate object permanence in 5.5-month-old infants and 6.5-month-old infants. In one experiment, 3.5-mon...

A collaborative study involving 8 laboratories was conducted to evaluate a method for the simultaneous determination of pesticide residues in 6 types of fruits and vegetables (spinach, tomato, apple, radish, cabbage and carrot). The method of analysis was the same as reported by Kakimoto et al. in 2003. One hundred and thirty-nine pesticides were spiked by each of 8 laboratories at levels of 0....

The valorization of fruit and vegetable residues (such as carrot discard) their microbial conversion into 2,3-butanediol (BDO) can be considered a very interesting way to reduce food waste sustainably originate high value-added products. This work analyzes the discard feedstock for production by Paenibacillus polymyxa DSM 365. influences stirring presence tryptone (nitrogen source) are studied....

in this study, production of fermented functional beverage based on the mixture of carrot, beet and apple juices using the lactobacillus casei was carried out. factors of consumption of reduction sugars, brix and bacterial growth were examined after fermentation and during the storage for 28 days and at 4˚c. to produce probiotic fermented mixture of carrot, beet and apple juices and lactobacill...

Embryogenesis was induced from regenerated carrot plantlets in a shorter time and at a higher frequency than that observed previously from hypocotyl explants of carrot seedlings (Masuda et al. J. Plant Physiol. 145, 531 (1995)). Serial observations of embryogenesis from single cells to globular embryos via cell clusters were possible in the conditioned medium. The ability to produce embryos see...

Reproduct ion of Pratylenchus vulnus Allen and Jensen on rose was repor ted faster at 32.2 C than at 23.9 and 15.6 C (6). Reproduct ion on alfalfa tissue was faster at 25 C than at 20 and 30 C (3), while on 'Lovell ' peach and bush bean, reproduct ion was faster at 28.3 C than at 24.4, 20.6, 16.7, and 12.8 C (1). Populat ions of P. vulnus and other species of root-lesion nematodes are often rai...

Byproducts of the processing foods are usually non-edible residues that typically discarded, even though they contain large amounts natural polymers with great potential in bioplastics and biocomposites preparation. Herein, a new method production vegetable-waste-derived is developed. It consists thermomechanical different presence small water, representing an advancement state-of-the-art compl...
